Abstract (en)

There is provided a copying system for copying information recorded on a first recording medium onto a second recording medium. The first recording medium is recorded with copying control information for representing conditions for permitting copying of the information recorded on the first recording medium, the copying control information being multiplexed within the information recorded on the first recording medium. Copying control information appears as a combination of two watermarks, WM1 and WM2, embedded as sequence of "0" or "1" at frequency f1 (resp. f2) with corresponding level threshold TH1 (resp. TH2). A modification section modifies copying control information when copying a disc.
